update
 

The new/used OMP from MazMart showed up Tuesday 2/26 and Steve got it installed on Thursday 2/28. That seemed to do the trick. They test drove it Friday and I picked it up that night. BUT, by Saturday I got a CEL. The car is not in limp mode though so I'll drive down to Autozone for the ODBII scanner to read and clear the codes. Looks like it'll be going back to R&R on Monday.

I'm torn between having my old OMP rebuilt for higher volume by Racing Beat and returning to Mazmart for my $100 core deposit.
